Motor Development

1 Head up in proneHands tightly fisted
2 Chest up in prone positionRetains rattle (briefly) if placed in handRolling prior to 3 months may indicate hypertonia
Head bobs erect if held sittingHands unfisted half of time

Anterior protection
6 Sits-props on handsTransfers objects hand-hand Embedded Image
Immature rake of pellet
7 Sits without supportRadial-palmar grasp of cube Embedded Image W-sitting and bunny hopping, may indicate adductor spasticity or hypotonia

Pincer grasp, held between distal pads of thumb and index finger Embedded Image
11 Stands alone
Walks with 1 hand held
12 Independent stepsFine pincer grasp of pellet between finger tips Embedded Image Failure to develop protective reactions may indicate neuromotor disorder
